A pipette for use with a pipette tip includes a housing, a pin on the bottom end of the housing holding a pipette tip having first means for form-fit connection and a second means for form-fit connection which can be shoved onto the pin, constricting the pin, and/or expanding the tip before form-fit connection with the pin, a drive apparatus, at least one locking sleeve arranged concentric to the pin which is guided toward the pin in the housing, wherein the locking sleeve has a locked position having a pin in the inside constricted by shoving on a pipette tip, and/or is bordered on the outside by a tip shoved onto the pin, preventing a release from the pin, and the locking sleeve is upwardly displaceable out of the locked position so that the pin, and/or the tip is released, and the tip is removable from the pin.

A culture flask comprising a culture chamber in a flask body comprising an even bottom wall with a growth surface on the top side, an even cover wall at a section from the bottom wall, and side walls that bridge the distance between the margins of the bottom wall and cover wall, an opening that is in adjacent regions of a side wall and the even cover wall at a distance from the bottom wall, and a hollow cylindrical flask neck that is connected to the margin of the opening and is aligned at a sharp angle to the growth surface so that the serological pipette, a scraper, a cannula or another elongated device for adding or removing material can be placed on the rear corners of the growth surface from the outside through the flask neck.

Culture flask

A screw cap lidded container for laboratory use includes a container body defining a chamber, a tubular section of the container body that is connected at the rear to the chamber and has a container opening in the front and an external thread on the outer periphery of the tubular section. There is a circumferential first sealing surface on the tubular section and at least one first projection, which projects from the container body at a peripheral position of the tubular section, and a screw cap having an internal thread on the inner periphery that can be screwed onto the external thread with thread play, a second sealing surface on the screw cap can be brought into sealing contact with the first sealing surface, and at least one second projection, which projects at a peripheral position of the screw cap.

A microtitration plate, having a frame made of a plastic which has a plate with a multiplicity of holes, and a multiplicity of receptacles made of the same plastic which are fixedly connected to the plate at the holes by directly molding them thereto, have a receiving portion protruding from the underside of the plate, and are accessible from the upper surface of the plate through apertures.

Microtitration plate

A microtitration plate for use for automated polymerase chain reaction (PCR) is provided. The microtitration plate includes a frame which has a plate with a multiplicity of holes molded of a polypropylene or a polycarbonate. The microtitration plate further includes a multiplicity of receptacles made of the same polypropylene or polycarbonate. The receptacles are fixedly connected to the plate at the holes by fusing the same polypropylene or polycarbonate thereby directly molding the receptacles to the plate Each receptacle has a receiving portion protruding from the underside of the plate, and is accessible from the upper surface of the plate through apertures.

Cover of a hybridization chamber with a peripheral frame with filling and ventilation holes extending from the upper face to the lower face of the frame, a peripheral shoulder outside the filling and ventilation holes on the lower face of the frame, a cover wall arranged within the frame, flush with its lower face and downwardly offset relative to its upper face and which substantially consists of at least one resilient plastics material.
